一、前言最近,我们用直径为950 mm 的大型螺旋桨进行了一次螺旋桨叶片上压力分布的精确测量。试验结果与表面升力理论不能始终保持良好的一致。因此,有必要深入研究螺旋桨周围除压力分布之外的速度和旋涡分布。并检查表面升力理论的流动模式,以进一步完善理论计算方法。
I. Introduction Recently, we used a large propeller with a diameter of 950 mm to perform an accurate measurement of the pressure distribution on the propeller blades. The test results can not always be in good agreement with the surface lift theory. Therefore, it is necessary to study in depth the distribution of velocity and vortex in addition to the pressure distribution around the propeller. And check the flow model of surface lift theory to further improve the theoretical calculation method.
